Auto align layers not working

I hope some of you can help me. I am trying to learn focus stacking and exposure bracketing. One important photoshop tool is to align different pictures when set up in layers. I have used different ways to achieve this, but photoshop is not able to align the pictures perfectly which I find odd. The problem must be with me , I suppose.  My setup is either nikon Z6 or Nikon D800 mounted on a tripod with the lens stabilisation turned off. I then take several exposures with different exposure or focus point (with some focus breething which is impossible to avoid). I make sure to group the photos so that I do not mix different focal length and so forth. When I import the pictures into photoshop to make magic , I have tried throu LR and make it open the pictures in different layers. I have also opened the pictures with ACR and arranged them in different layers in photoshop. When I auto align the layers they always seems some pixels off (from 5 to 10). The same happenes when I import directly in photoshop script stack (did I write that correctly ?) . From time to time the alignment is perfect, but most of the time not. The pictures are typically ordinary landscape pictures, where there are a lot of detail, and most pixels should be almost perfect aligned to begin with ( pre alignment) . I do not use smart objects (I am not smart enough). So I think I follow the tutorials, but my photoshop (latest edition subscription) does not deliver. The tutorials I watch arrange the picture in layers, and then choose auto-align and voila , it works. Not with me though. When clicking one layer on and off afterwards, with som magnification, you clearly see it "jumping" slightly , most often to one side, seldom upp and down. So, please tell me what I am doing wrong ?? I use a windows 11 laptop (problem present when I used windows 10), the CPU, GPU , SSD and RAM is sufficient for DaVinci Resolve and should not be an issue , I belive.
